Which of the following pairings are more likely to be held together with the strong nuclear force?

aivan3 [116]

Which of the following pairings are more likely to be held together with the strong nuclear force

Explanation:

1.What does a strong nuclear force do in an atom? It repels electrons from other electrons. It repels protons from other protons. It attracts protons and neutrons.

2.The chain reaction requires both the release of neutrons from fissile isotopes undergoing nuclear fission and the subsequent absorption of some of these neutrons in fissile isotopes.

3.The strong nuclear force holds most ordinary matter together because it confines quarks into hadron particles such as the proton and neutron. In addition, the strong force binds these neutrons and protons to create atomic nuclei.

You buy a magnifying glass at the store. The lens in the magnifying glass is a double convex lens, a lens with two convex curved

Leokris [45]

Answer:

30 cm

Explanation:

f = Focal length = 25 cm

R = Radius of curvature (both sides are equal)

$\mu$ = Refractive index of lens = 1.6

The lens maker formula is given by

$\frac{1}{f}=(\mu-1)(\frac{1}{R_1}-\frac{1}{R_2})\\\Rightarrow \frac{1}{f}=(\mu-1)(\frac{1}{R}-\frac{1}{-R})$ minus sign because it is on the other side

$\\\Rightarrow \frac{1}{f}=(\mu-1)\frac{2}{R}\\\Rightarrow R=2(\mu-1)f\\\Rightarrow R=2(1.6-1)\times 25\\\Rightarrow R=30\ cm$

The radius of curvature of the glass surface is 30 cm

A scientist hypothesizes that the temperature at which an alligator's egg is incubated will determine whether the alligator will

WINSTONCH [101]

Answer:

The independent variable its A, the temperature.

Explanation:

There are two variable in this (mental) experiment. The temperature and the gender of the alligator.

The temperature its the independent variable, its the one we can control using the incubator.

The gender of the alligator, its hypothesized, will be determined by the temperature, so, its the dependent variable in our hypothesis.

The incubator will be used in all the eggs of the experiment, so, its not a variable.

The male alligators its one of the possible outcomes of the experiment. Again, not a variable.

Which wave would produce a standing wave when combined with the original one

Elden [556K]

Answer:

When original wave superimpose with its own reflected wave travelling in opposite direction then it will produce standing wave

Explanation:

Let say the equation of original wave is

$y_i = A sin(\omega t + kx)$

now the equation of its reflected wave which is reflected 100% is given as

$y_r = A sin(\omegat - kx)$

now by superposition of above two waves we will have

$y = y_i + y_r$

$y = A { sin(\omega t + kx) + sin(\omega t - kx)}$

$y = 2Asin(\omega t)cos(kx)$

so above shows the equation of standing wave

so we can say that When original wave superimpose with its own reflected wave travelling in opposite direction then it will produce standing wave
